Russell Performance 645263 45-Degree Swivel Coupler Adapter Fittings Set

These reusable AN swivel couplers allow for the straightforward connection of AN hose ends and hardlines across a wide range of fuel, oil, and coolant system configurations.

Constructed from heat-treated aluminum, each coupler features a 45-degree angled body that simplifies routing in tight engine bay spaces. The swivel design allows both ends to rotate independently during assembly, eliminating hose twist and making installation significantly easier. The female-to-female AN flare interface creates a leak-free 37-degree JIC seal when mated with standard AN male fittings or hose ends.

Key Features:

• 45-degree swivel coupler configuration for flexible routing
• Reusable swivel design reduces assembly stress and hose twist
• Lightweight heat-treated aluminum construction
• Anodized finish for corrosion resistance and long service life
• Female AN flare to female AN flare (female-to-female) interface
• Compatible with standard 37-degree JIC AN hose ends and hardlines
• Universal fitment — suitable for fuel, oil, brake, and coolant plumbing

Russell Performance adapter fittings are a trusted choice in motorsport and high-performance street applications, offering a broad selection of configurations to accommodate nearly any plumbing layout.
